SPECIFICATION forming pareof Letters Patent'No. 741,715, dated october2o, 1903.

Application led March 25, 1908. Serial No. 149,449. (No model.)

To ar/ZZ whom t r11/ay con/cero@ Beit known that I, CHARLES A. ANDERSONRAND, a citizen ofthe United States," residing at Chicago, in the countyof Cook and State' of Illinois, have invented a 'newand usefulImprovement in Reel-Rakes for Reapers, of

switch-latch lifter init-s horizontallyvibrat` ing movement by exertinga differential stress upon the pivotally-mounted index-quad rant; whichpivotall y su pports the said switch-latch' lifter.

Another feature of the invention lies in theA novel construction of theswitch-latchlifter, in which yan upwardly-extending arm h2 thereonengages the switch-latch in such a manner and at such a predeterminedtime as to render inoperative the s aid switch latch, thereby allowingthe spring to hold the switch in its open position except whenmomentarily closed by the rollers on the rake-arms passing therethrough,and-thus permit every rake to sweep the table.

The construction set forth in this invention will enable the rake-armsto be caused to sweep the platform every second,third, fourth, or fifthtime, not at all except when the foot'- trip ismomentarily depressed, orevery time except when the foot-lever is held depressed.

To whatever position the parts are adjusted and with whatever frequencythey cause the rake-arms to sweep the table they are at all timessusceptible to the action of the foot-- lever-that is to say, inwhatever position the index-lever is placed movement of the footleverwill operate tolift, and thereby render inactive, the switch-latch.Heretofore the arrangement and construction of the switchactuatingmechanism in connection with the foot-trip have vbeen such that whenreleased position.

I by the latch the switch could swing open at a time havingv no definiterelation to the position of the approaching rollers of the rakearm, andin consequence the switch would occasionally intercept and stop the saidroller.

This difficulty has been overcome in the present invention by causingthe switch to a1- wa'ys open at a'denite time relative to theapproaching rollers.

' While most of the elements comprising the switch-actuating mechanismin this invention may be regarded as modifications of correspendingparts already known inthe art, yet for clearness it is `thought 'best tostate that the distinctively new features are the following: the arm h2,projecting upwardly from the latch-lifter H and in a position adaptingitA to hold the latch J out of engagement with the switch-lock arm e',the shoulder-j8 on the said switch-latch J, adapted to engage the arm h2when the index-lever isset at its lower limit, and thus permit thespring K swinging the index-quadrant 'and supported parts in against theworm, the spring K having the double function, as hereinafter set forth,and the foot-trip cam L, operating in connection with the latch-liftingdevice to trip the latch.

Referring to the drawings, Figure 1 is a rear elevation of areaper-stand with the rakearm operating and tripping mechanism supportedthereon. Fig. 2 is a side elevation, partly in section, of the same,taken as indicated by the broken line 2 2 onFig. 1. Fig.. 3 is a plan ofthe rake-arm roller-cam, the switch and bridge being shown in theirclosed Fig. 4 represents the same view with the switch and bridge shownin their open position. Fig. 5 isa plan of the switch andswitch-operating mechanism, the switch being shown in its closedposition and the toothed segment of the switch-latch lifter being shownin mesh with its acmating-Worm.v Fig. 6 is a corresponding view with theswitch shown in its open position and the toothed segment of theswitch-latch lifter swung to a non-engaging position relative to theengaging worm. Fig. 7 is a vertical section through Fig. 5 as indicatedby the line 7 7 in that IOO a plan View of the parts shown in Fig. 7.Fig. 9 is a plan section of the spring-actuated iudeX-lever-engagingpin. Fig. 10 represents a perspective view of the switch-latch. Fig. 11is a fragmentary plan section as indicated by the lines 11 11 in Fig. 2,illustrating the arrangement of the coil-spring in connection with theswitch and index-quadrant. Fig. 12 is a View in perspective of thefoot-trip cam; and Fig. 13 is a fragmentary view in perspective ot' aportion of Fig. 2, showing the manner in which the upwardly-projectingarm on the switch-latch lifter sustains and holds the switch-latch fromengaging the switch-lock arm.

In the drawings, A represents the rakestand; B, the rake-cam,consisting, essentially, ofthe cam-track and bolted to the rakestand,and C is the rake-head or spider, to which are pivotally secured therake-arms D. A is the sprocket-wheel, mounted on the shaft A2, throughwhich motion is imparted to the mechanism mounted on the rake-cam. Onthis shaft A2 is secured the bevel-pinion A3, which meshes with thebevel-gear A4, mounted upon the vertical shaft A5. To this shaft A5 aresecured the worm A5 and the spider C. The spider C supports and drivesthe usual rake-arms D, which in turn are provided withantifriction-rollers (Z, adapted to follow the track on the cam B, andthus control the movement of the free end of said rake-arms. Inconstruction the rake-arms comprise the rake-arm sockets and therake-arms proper, only a fragment of the rake-arms showing, however, inFig. 1; but for convenience in description both members will hereinafterbe understood to be included in the term rakearm. Pivotally mounted uponthe rake-cam B are the bridge B' and the switch E, which, with the otherparts mentioned, maybe of any preferred construction, as they are partscommon to this type of machine. The function of the bridge and theswitch is the same as that performed by the corresponding parts inmachines of this class, the switch operating to either permit the rollerd of the rake-arm D to follow the regular cam-track, and thus allow saidarm to sweep the platform, or to deflect the said roller upon the bridgeB', which will operate to raise the arm above the table. The pivotalconnection of the bridge will permit its free end to swing out andpermit the roller d to continue its travel on the regular cam-track orswing in when the roller has been deflected upon it and in this way forma continuous track in a position which will permit the rakearm to sweephigher above the table in a manner well understood.

The stem c of the switch E journals in a bear.

ing bin the rake-cam casting B, (see Figs. 1 and 2,) its axis beingvertically disposed, and the said switch is operated by thefollowingdescribed mechanism:

Rigidly secured to the lower end of the stem e of the switch E and asone piece with said switch is the switch-lock arm c, and integral withthe hub portion of this arm is the projecting lng e2. (See Fig. 1l.)Through this switch-lock arm e the switch itself is either released orheld closed by the switchlatch in a way hereinafter more fullydescribed. Parallel with the axis of movement of the switch extends thestub-shaft or, preferably, a bolt g, journaling in a bearing b', formedin the rake-cam B. This bolt g may be and, in effect, is a spindle asone piece with the bridge B'. Sleeved upon this bolt immediately belowthe bearing h' is the index-quadrant G, as shown in the general views 1and 2 or in the detail views '7 and S. This index-quadrant is free toswing horizontally on its pivotal bearing within certain limits, andintegral with the hub portion thereof and extending transversely theretois the bearing g', in which journals the spindle as one piece with theswitch-latch lifter I'I. On the projecting end ot' the spindle h sleevesthe index-lever I, the free end of which is provided with a pin fi,adapted to engage one of the series of apertures g2 in theindex-quadrant G. The pin i is provided with a coil-spring i for holdingit in engagement with the quadrant, as shown in detail in Fig. 9. Theengaging portion of the index-lever is provided with a recess in whichlies the edge of the segment of the indexquadrant, thus affording atwo-point support for the said pin t', as is also shown in Fig 9.Integral with the free end of the index-lever I and beyond the peripheryof the said index-quadrant is the stop 2, which projects into the pathof movement of the switchlatch lifter H, as shown in Figs. 7 and 8. Onthe switch-latch lifter H is a foot h', adapted to rest upon the stop i2of the index-lever I, thus supporting the said switch-latch lifter in aposition depending upon the height to which the index-lever is set.Projecting upwardly from the latch-lifter I-I is the arm h2, situated ina' position which will adapt it to engage and support the switch-latch.I (see Figs. '7 and 13) when the pin /z on the indexlever I engages thelower aperture in the index-quadrant, this arm h2 being for a purposehereinafter more fully stated. On the latchlifter H is a series 0f teethh3, designed to mesh with the worm A6 when contacting the same and inthis way effect the raising of the said latch-lifter.

Mounted on the hub Z) of the switch-spindle hearing (see Figs. l and 2)is the coil-spring K, oneend 7c of which is turned down and engages thelug e2 of the switch-lock arm e', the other end of the spring-Wirebearing in the grooved recess g3 in the projecting lug g4 on the upperportion of the hub of the indexquadrant Gr. (See Figs. 5 and (i.) Theeffect of this arrangement will be to cause the short arm f. to exert astress tending to open the switch E (see Figs. 5, 6, and 11) and tocause the long arm 7c' to exert a less stress, tending to rotate theindex-quadrant, with its attached parts, to a position bringing the TOCteeth h3 of the latch-lifter to mesh with the teeth of the worm AG. (SeeFig. 5.) The lug g4 is of a length sufcient to enable it to impinge theprojecting lug e2 on the latch-lifter arm e'. This lug c2 serves as astop to prevent movement of the quadrant G about its pivotal axis causedby the pressure of the spring K, and it also operates to disengage fromcontact the latch-lifter H and the worm A6 when said spring `K causesthe switch E to swing open, as shown in Fig. 6.

The switch-latch J pivots on the pin j, (see -Figs. 'and 6,) which issupported by the downwardly-projecting ears b2 b2, integral with therake-cam B, and near the outer end of said latch is the hook j', adaptedto engage the switch-lock arm e', as shown in Figs. 2 and 5. t7'2 is afoot (see Figs. 5 and 6) on the said latch J, so located that it will beimpinged by the lug h4 on the switch-latch lifter .H as said lifter iscaused to rise byits teeth engaging the worm A6. f3 is a small shoulderon the side of the latch 'J, the function of which is to engage the armh2 of the latchlifter at a certain time "and prevent the arm 7c of thespring K'swinging the said latchlifter. The projecting spur g5 at theupper end of the boss of the index-quadrant G contacts one of the lugsb2 and acts as a stop to limit the outward swing of said lever G.

Loosely sleeved upon the bolt g and below the hub of the index-quadrantG is the foottrip cam L, provided with the cam portion Z, (see Fig. 12,)which bears against the cam portion h5 of the latch-lifter H. Z is a pinwhich engages the rod Z3, (see Fig. 8,) which actuates the foot-tripcam, and Z2 is a shoulder which contacts the projection g6 on theindex-quadrant G when the said foot-trip presses the said quadrantawayfrom theworm.

The operation of the switch-actuating details is as follows: Should itbe desired to have each alternate reel-rake sweep the platform, as mightbe required in excessively heavy grain, the index-lever I is raised andsecured adjacent to the' upper aperture g2 in the index-quadrant bymeans of the pin v1. The latch-lifter H through its foot h, which restsupon the projecting lug Z2 of the indexlever I, will be correspondinglyraised, so that the toothed segment thereon will engage the worm A6 at apoint near the bottom of said segment, the eifect of which will be tolessen the distance between the lug h4 on the said latch-lifter and thefootj2 on the switch-latch J. In consequence of this the worm A6,raising the latch-lifter H, will cause it to release the latch J andopen the switch sooner. The rate of speed at which this latch-lifter ismoved by the worm is so timed by the pitch of their respective teeththat,assuming that the switch is closed, only one roller CZ of therake-arms D will have passedaround the switch E and upon the bridge Buntil the switch-latch lifter will have engaged and released theswitch-latch J from the switch-lock arm e', thus allowing the spring Kto open the switch and permit of its path and in so doing closes theswitch to its locking position. The closing of the switch will at thesame time bring the toothed segment of the switch-latch lifter again'inmeshy with the worm, and in another equaly period of time theswitch-latch will again be released and the switch again opened. Theclosed position of the switch is shown in Fig. 5 and its open positionin Fig. 6. An inspection of Fig. 6 will show that if theinwardlyprojecting arm e3 of the switch be pressed by the roller in adirection to throw the switch to a closed position 'the long arm lc ofthe spring K will bear against the projecting lug g4 and cause theindex-quadrant, With its supporting parts, to swing in contact with thesaid worm, as shown in Fig. 5. When the switch-latch is released, theabove-referredto parts are swung to the position shown in Fig. 6 by theshort lug c2 on the switch-lock arm bearingagainst the end of thelongprojecting lug g4. The stress exerted by the spring K upon theindex-quadrant. and supported parts is greater in the opening ordisengaging movement of these parts than in the closing or engagingmovement thereof. This Vis due to the fact that in the opening movementthe stress is applied to the moved parts through the long lever gby theshort and consequently more effective arm 7c of the spring K actingthrough the lug e2, while in the closing movement the operated parts aremoved by a long arm Zo of the said spring K acting upon the shortportion of the armgl. It. follows that the spring K will when theswitch-latch J is released swing the switch to its open position andsimultaneously disengage the toothed segment on' the switch-latch lifterfrom the worm. To cause the rakearms to sweep the table every third,fourth, or fifth time, the pin i is placed in the second, third, orfourth hole, respectively, fronrthe top in the index-quadrant G. Becauseof this drop of the index-lever the switch-latch lifter will necessarilyhave to be raised a correspondingly greater distance,and as in thefirst-described operation the timing is such that the lug h4 will notimpinge the footj2 on the switch-latch until either two, three, or fourrollers have passed over the bridge, when the latch will be released andthe switch opened, as previously described, the next roller followingthe regular track on the cam, and thus allowing that rake-arm to sweepthe table.

If the pin t' is made to engage the fifth hole from the top, the teethon'the switch-latch lifter will be allowed to drop down to a position inwhich engagement with the wormA6 is no longer possible, and hence asthere is no such engagement the switch-latch willv remain locked andevery roller made. to 'pass' Ion IIO

over the bridge, the rake-arms serving only to reel the grain to theplatform. In this position, however, if the foot-trip cam is swungaround on its pivotal bearing it will cause the latch-lifter to beraised to a position where its teeth will engage the worm, and hencecause the switch-latch to be tripped. In this way the foot-trip actsindirectly to trip the latch, the tripping being elfected in the usualmanner by the worm raising the latch-lifter after it has once beenengaged. This arrangement will insure the switch being released at acertain definite time relative to the movement of the other parts, andhence the point of the switch will never intercept the rollers of therake-arm. If in this last position the foot-trip cam is held in contactwith the switch-latch lifter, it will not only raise the lifter, but theshoulder Z2 on the said foot-trip cam will bear against the shoulder gGon the index-quadrant and press the toothrack out of engagement with theworm, thus rendering the tripping mechanism inoperative as long as soheld.

If the pin i2 is placed in the lower hole of the index-quadrant, thehorizontally-extending arm thereof will have dropped so low that theupwardly-extending arm 71.2 of the latchlifter will have moved forwardto a position where it will prevent the latch J from dropping over thelock-arm c', as shown in Fig. 13. This will render the switch-latchinoperative and permit the switch to open for every roller, thusallowing each arm to sweep the table and swath the cut grain. The arm h2on the latch-lifter impinges the shoulder jg on the switch-latch .I whenthe switch is closed, and thus prevents the index-quadrant and supportedparts swinging in and out every time the switch is closed and opened.

It is of course necessary to the successful operation of the switch andactuating-rollers on the rake-arms that the distance between thesuccessive. rollers on the said rake-arms be slightly greater than thetotal length of the switch.
